Using Multiple Electrical Apparatus
However, a potential hazard may occur if the enclosure leakage currents from multiple
pieces of equipment combine and are inadvertently routed directly to a patient's heart
via a catheter or pacemaker lead. Only equipment which is certified to IEC and
ANSI/AAMI medical standards should be used in this environment. Use of certified
equipment does not, however, completely eliminate this possible hazard.
Another potential hazard may occur if two devices near a patient are powered from
different circuits. If the grounds of the two circuits are at different potentials, which can
occur under certain fault conditions, then a ground loop can exist between the
enclosures of the two devices. If devices must be powered from separate circuits in the
vicinity of a susceptible patient, then the grounding lugs on the devices should be
electrically connected via an equipotential cable. Please also consult Chapter 2,
"Equipment Setup."
